Lyrics not being updated on my iPod touch

Hi, I'm trying to modify lyrics via iTunes, but it never updates on my iPod Touch where iTune shows an updated lyrics on get info>lyrics.

Things I tried and yet to find a solution:
1. Delete, add the music with updated lyrics to my Touch.
2. Uncheck manual managing. The song on my iTune library gets the older version of the lyrics every time I sync.
3. Hard reset iPod Touch.
4. Restore to default settings.

For example, my song has lyrics of "Thakn you for helping me."
I put this song into my Touch, but I figured there is a typo so I change it to "Thank you for helping me." on my iTune library. Then I delete the one in my Touch then re-add the updated song.
My touch still says, "Thakn you for helping me."

Now, that's just an example and I'm not asking for help just so that I can edit typos. Most of the songs have lyrics on Unicode so I had to edit it in order to view it.

Please it will be really appreciated if you could help. Thanks.

I had to figure out myself since no one knew how to solve it.
Well, I located the cause and solved it.
